Surface Preparation for I
Polyurethane red iron oxide anti-rust primer (2K) for steel structures and long-term anti-corrosion.
For steel structures anti-rust priming.
Mixing ratio 4:1; pot life 3 h.
Compatible with polyurethane and acrylic polyurethane topcoats.
Overview
Two-component anti-rust primer with fast drying and low-temperature applicability.
Features include very good adhesion, anti-rust performance, and resistance to oil and water.
Composition
Based on hydroxyl-containing resin, premium red iron oxide anti-rust pigment, refined fillers, additives, and solvents.
Cured with polyisocyanate prepolymer; supplied in Part A & Part B packs.
Typical uses
Anti-rust primer for all steel structures.
Also suitable for long-term anti-corrosion on concrete and aluminum alloy surfaces.
